The function g(x) is defined as shown. x-1, -2 g(x) = 2x+3, -1 6-x, x23

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).

The radical equation 2+√2x-3 = √x+7 has a solution set [x= a0} and an extraneous root x = a1.
